SMOKE-CONSUMER.

SPECIFICATION forming part of Letters Patent No. 417,411, dated December 17, 1889. v

Application filed May 28, 1889. Serial No. 312,428. (No model.)

To a/ZZ whom it may concern:

` Be it known that we, EBENEZER DANFORD and CHARLES E. A. SAGLE, citizens of the United States, i residing at Aurora, inv the county of Kane and State of Illinois, -have invented certain new and useful Improvements in a Smoke-Consumer, of which the following is a. full, clear, and exact description, that will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

i The object of this invention is to provide an improved vdevice to be placed in the furnace of steam-,boilers for the purpose of promoting` colnbustion by consuming the volatile gases, which, Linder the ordinary arrangement, escape into the atmosphere in the form of smoke.

This invention relates to that class of smokeconsuming devices wherein a mixture of steam and air are injected into thefurnace; and the same consists of certain novel features in the construction, arrangement, and operation, as will be hereinafter set forth.

This invention is more especially intended for use on locomotives, and that style of a boiler-furnace is used to illustrate a practical application of my improved attachment; but it is obvious that the device may be applied to stationary and other boilers.

Figure 1 is a broken-away vertical longitudinal section of a locomotive-boiler in plane l, Fig. 2, showing the relative position of my attachment; Fig. 2, a vertical transverse seci tion in plane 2, Fig. l, looking in the direction indicated by the arrow; Fig. 3, an enlarged sectional detail showing the relative position and manner of supporting the device when attached to a locomotive-boiler. Fig. 4 is an enlarged longitudinal sectional view of the injector.

In the drawings, A represents the boiler; A', the water-jacket part of the same; B, the

' furnace or combustion-chamber inclosed by said jacket; B', the line of the grate-bars; O

the furnace-door and D the steanr and air heating and distributing pipe.

The pipe or heater D is arranged transversely in the furnace, and is located close to the back shell of the water-jacket, leaving just suiiicien't space for the heat to pass clear around the same, as shown in Fig. l. This pipe D will be a little above the fuel-level, and is provided with a number of elongated apertures or slits a a on that side facing the furnace-door, as shown in Figs. l, 2, and rlhe lower row of apertures a opens in a horizontal plane, and will inject the air and `steam received into the pipe D across the level of the upper part'of the combustion-chamber and4 supply fresh oxygen to consume the gases before they pass into the iiues.

The apertures a a in the pipe D alternate with reference to each other so as to cover the entire space. The elongated slits, being quite narrow, inject the steam and air in thin sheets, and thereby have the result of creating a more perfect combustion than if `injected through round perforations. l

The sides of the furnace or water-jacket are perforated,and a thimble E inserted so as to be steam and water tight. The tube F is placed inside of the thimble and projects into the respective ends of the pipe D, and supports the same in the manner shown in Fig. 3, which arrangement provides for expansion and contraction.

The injector proper consists of the outer steam-nozzle G, (see Figs. 3 and 4,) having the tapering discharge end inserted in the outer end of the tube F, and the air-nozzle H inserted inside of the steam-nozzle and having an adjustable threaded engagement therewith, as at a2, Fig. 4. the air-nozzle terminates in the contracted passage as of the steam-nozzle, and stops short of the discharge end thereof, the end of the air-nozzle being correspondingly contracted, so that a greater or less volume of steam may be admitted in accordance with the direction in which the air-nozzle is turned. The airnozzle 4is provided with the head a4 as a convenience in adjusting the same. a is a steam- The discharge end of TOO space between the two nozzles. The pipes b b' conduct the steam used from the boiler to the companion injectors located on each side of the boiler, as shown in Fig. 2. The arrangement and parts illustrated in Fig. are in duplicate.

The pipe D is provided in its longitudinal center with the partition d, as shown by the broken-away part in Fig. 2. This partition prevents the two volumes of air and steam entering from affecting each other, thus insuring a more equal and uniform distribution of the mingled steam-and-air jets. By this arrangement the proportion of steam admitted can be regulated to a nicety, and the air and steam are heated to a high degree of temperature in the pipe D before being injected into and caused to eommingle with the volatile gases generated in the furnace, thus greatly increasing the inflammable'character of the same and insuring perfect combustion. j

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a slnoke-consuming device, the combination, with a boiler-furnace or combustionehainber, of a perforated heating-pipe arranged transversely in the furnace at the rear side thereof, above the fuel-level, and communicating at'both ends with the outer atmosphere, the partition placed in the longitudinal center of said pipe, and the combined steam-and-air injector discharging into the respective ends of said heating-pipe, and consisting of the outer steam-nozzle provided with a steam-inlet opening in the side and the air-supply nozzle adj ustably inserted in the steam-nozzle, both of said nozzles having contracted discharging ends, the discharge end of the air-nozzle stopping short of the corresponding end of the steam-nozzle, whereby the volume of steam and air admitted is thoroughly commingled and heated before being discharged into the furnace, substantially as set forth.

2. In a smoke-consumer, the combination, with a heating and distributing pipe receiving air and steam at both ends, of a partition placed in the longitudinal center of said pipe, as set forth.

3. In a smoke-consumer, the combination, with the combustion-chamber, of the steam and air heating and distributing pipe arranged transversely therein, the water-jacket inclosing t-he furnace and having openings through both sides, the thimbles rigidly secured in said openings, the tubes inserted in said thimbles and projecting into aud supporting the respective ends of the heatingpipe, and the injectors inserted in said tubes and consisting of the outer or steam nozzle and the inner air-nozzle tapering at their discharge ends and adj ustably secured with relation to each other,whereby the proportion of steam admitted with reference to the airj supply may be easily regulated and the volume of steam and air thoroughly eommingled and heated to a high degree of temperature before being discharged into the lire, substantially as and for the purpose set forth. y
